Application May 18, 1950, Serial No. 162,736 7 Claims. (Cl. 15S-184) This invention relates to improvements in edge rolls for use in upholstery.

The main objects of this invention are:

First, to provide an edge roll for upholstering which is well adapted for upholstering spring assemblies and the like and which may be quickly and easily applied and is very securely mounted and maintained in proper relation to the spring assembly.

Second, to provide an edge roll for upholstering which may be very veconomically produced and is adapted for a wide range of uses.

Third, to provide an edge roll having these advantages in which the parts are so arranged and. associated that the stresses in use are widely distributed rather than being localized.

Other objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in kthe claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

Fig. l is a fragmentary plan View of a spring 'assembly with the edge roll of the invention 4mounted thereon.

Fig. 2 is an enlarged transverse section of the edge roll of the invention.

Fig. 3 is a fragmentary transverse section on a line corresponding to line 3 3V of Fig. 1.

Fig. 4 is a fragmentary inverted view of the edge roll of the embodiment shown in Figs. l, 2 and 3.

Fig. 5 is a fragmentary perspective view of a 4moditied form or embodiment of the invention and showing the adaptation to a frame piece of an article of furniture as distinguished from a spring assembly.

Fig. 6 is a fragmentary perspective view of another modified form or embodiment of the invention.

in the accompanying drawing we have illustrated in Figs. l and 3 an embodiment of the invention applied to a spring structure, fragments only being illustrated. In these illustrations 1 represents the top border member and 2 a coil body spring and 3 a fabric covering for the spring assembly. Our improved edge roll in the embodiment illustrated in Figs. 1 to 4, inclusive, comprises a resilient body 4.

The resilient body 4 illustrated is of cylindrical section and is provided with a wrapper 5 which is braided thereon to closely embrace the body material and with the strands 6 of the wrapper extending spirally of the body. The outer covering 7 is formed of open mesh woven material and is Wrapped around the body with edge portions thereof projecting from the body in side by side relation to constitute ap extensions or elements 8. Flap strips 9, preferably of flexible paper, are disposed on opposite sides of the ap extensions 8 and Vclosely adjacent the body and adhesively secured thereto and to the ap extensions by adhesive indicated at 10 which penetrates the covering or embeds the strands of the covering as is illustrated in Fig. 2. The strips 9 preferably have laterally projecting inner edge portions 11 which are secured in part, at least, to the body as indicated at 12. The

paper strips constitute means for confining a mass of adhesive around the strands of the open mesh fabric and in the open spaces between said strands, as shown in Fig. '2. The paper strips confine the adhesive when these strips and the flap extensions are adhesively connected to each other. With the mass of' adhesive so conlined the flap extensions 8 can be securely connected to each other closely adjacent to the resilient body 4 so that the open mesh covering is tightly held around the resilient body. It is dcult to so hold the covering around the core by stitching, as heretofore done, due to the open mesh of the fabric. The paper strips with the adhesive co-nned thereby as above described permits the use of the relatively cheap open mesh fabric as a covering for the resilient body and securely holds the same tightly around such body.

ln the embodiment of Figs. l to 3, inclusive, we provide a beading cord 13 which is preferably formed of twisted paper and this is pressed into the side of the body over its wrapper as is shown in Fig. 2 and adhesively secured thereto at 14. The covering is on the outer side of the beading cord. ln installing on a spring structure, for example, the ap, which may be designated generally by the numeral 15 and constituted as we have described, is secured to the springs or other parts of the spring assembly as by means of clips 16 commonly designated hog rings in the spring art. Similar clips are employed in securing the beading element 13 to the border wire as is shown in Figs. l and 3. ln the embodiment of our invent-ion illustrated in Fig. 5 the beading cord is omitted and the flap strips 17 are arranged upon and secured to the flap extensions S of the covering adhesively but these strips 17 are of desirably substantially thicker stock than the strips in the embodiment described. Where the furniture or other parts to be upholstered is provided with frame pieces as 1S, upholstery or other tacks 19 may kbe employed, these being driven through the ap into the frame.

in this adaptation the beading cord is omitted. The body 4 may be desirably formed of twisted paper, jute, yor other resilient iibrous material.

In the embodiment of the invention shown in Fig. 6 the body 20 is formed of longitudinally extending twisted strips of paper and the braided wrapper is omitted. The -covering 21 in this embodiment is desirably more closely woven than the covering 7 in the embodiments of Figs. 1 to 5, inclusive, a somewhat loosely woven burlap covering being suitable for many uses. It is arranged, however, with certain of the strands encircling the body and the fibrous flap strips 22 are secured to the flap extensions 23 of the covering by means of adhesive extending through the mesh or between the strands of the fabric covering as indicated at 24. All three of the embodiments illustrated are highly practical and desirable.

We have not illustrated or described other modifications or adaptations which we contemplate as it is believed that these disclosures will enable those skilled in the art to adapt or embody our invention as may be desired.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

l. An edge roll for use in upholstering camprising an elongated resilient body of resilient fibrous material enclosed in a wrapper braided thereon with the wrapper strands extending spirally around the body and in embracing contining relation thereto, an open mesh woven covering disposed over said body wrapper with the edges of the covering disposed in projecting overlapping relation providing ap extensions, strips of paper disposed on opposite sides of the said flap extensions and adhesively secured together through the mesh of the covering with the adhesive embedding the strands of the covering, and a longitudinally disposed beading cord disposed between the braided wrapper and said covering in spaced parallel relation to the flaps and adhesively secured to the body through the mesh of the wrapper, the body having a longitudinal recess in which said cord is disposed.

2. An edge roll for use in upholstering comprising an elongated resilient body of fibrous material enclosed in a wrapper braided thereon with the wrapper strands extending spirally around the body and in embracing conlfining relation thereto, an open mesh woven covering disposed over said body wrapper with the edges of the covering disposed in projecting overlapping relation providing flap extensions, strips of paper disposed on opposite sides of the said flap extensions and adhesively secured together through the mesh of the covering with the adhesive embedding the strands of the covering, and a longitudinally disposed beading cord disposed between the braided wrapper and said covering in spaced parallel relation to the aps and adhesively secured to the body through the mesh of the wrapper.
